STY 3-5kVA Desktop model
It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop

Heavy Duty AVR 3/3 phase 50-2000kVA

Three-wire AC voltage Regulator is composed of;
- Three phase compensation transformer
- Three phase regulating and insulating transformer
- Transmission system
- Brush contact system
- Box body and control system
Key Features
- Sampling circuit transfer signal to synchronous machine
- Synchronous machine guide the brush regulating
- Assure the output waveform stable. When the outside power supply network voltage fluctuates or the load changes to make the voltage undulation
- Three wire AC Voltage Regulator can automatically maintain the output voltage to be stable.
